IMPROVEMENT IN VISES.

Specification forming part of Letters Patent No. v150,180, dated April28,1874;y application filed 'y i October 20, 1873.

To all 'whom t may concern Be it known that I, EDWARD L. MORRIS, ot'-dial hole formed in the screw-shaft, and, being thus restricted in itsposition, stands often in the way of the workman or the work to besecured in the vise, and, being also the only means of operating` thescrew, of necessity makes said operation slow and bungling. The objectof my invention is to overcome the dis! advantages above mentioned, andalso to ad! mit of the use of a very long lever without interfering withthe convenient working of said screw. My invention consists in thevconstruction of the screw-shaft of a vise for the interlock of a levertherewith, and in the combination, with the said screw-shaft, of alever, which is hung loosely thereon in such a manner that when not usedto operate the screw-shaft it shall hang at rest, not affecting theaction of the screw, or being affected itself by the action of thescrew, and when required for operating said screw-shaft it can bereadily interlocked with and made to seize the screwshaft for turningthe same, and thereby secure a firm gripe of the article between thejaws. My invention further consists in the combination with ascrew-shaft and a lever, each constructed and arranged for operation, asabove described, of a crank permanently attached to the saidscrew-shaft, by which crank the movable jaw of the vise may be readilyadjusted to about the size of the article to be secured therein beforeengaging the lever with the screw, to give greater purchase to securethe work firmly in the vise.

In the accompanying plates of drawings the present invention isillustrated by views showing the same in various forms of construction,but all involving the principle of the invention, as hereinbeforestated; and in these plates- Figure l is a longitudinal vertical sectionon the line of the axis of the screw. Fig.; 2 is 'a transverse sectionon .lineay x; of Fig. 1. Figs. 3, 4, 5, 6, 7, 8, and Qfaredetached viewsin detail, illustrating different modesot' carrying out my invention,which-viewswillfibe hereinafter particularly referredto..I

In the drawings, Figs. l and2, Avis the-fixed jaw and B the movable jaw.The jaw A is provided with the nut C rmly secured therein for the screwD towork in, to move thejaW B. The screw D issecured by-meansvof-itsgroove c and the screw-pin b,fasrshown, and all of the above in itsconstruction and .operation is well known vand common. The: screw D isprovided with an enlargementoutside,of the jaw B, and in the peripheryof this enlargement are formed a series ofradial holes vor sockets, c,as shown in Figs.' l and 2.; Eis "a lever, provided at one end withanoblonghole or slot, E', which embraces the enlarged.-por tion of thescrew, and the *levery depends -perpendicularly from-the screw,- when atrest, as shown in- Figs. l and 2. Y The-oblong hole -E of the lever Ehas a pin, d, at its lower side, which pin projects toward the center ofthe hole E', and in its length is such that when the lever depends .fromthe shaft it will not interfere with` the turning of the shaft. F is asmall wheel, secured to the outer end of the screw-shaft D, to be usedas a hand-wheel, or it may be provided vwith* the crank-handle G, or asimple crank may be substituted for the wheel, if desired. operate thescrew D for adjusting the jaws to about the size of the article to besecured therein. The wheel F, under the construction shown in Figs. 1and 2, also serves to hold the lever against escape from the shaft D,and furthermore, together with the jaw B, as a guide to the lever ininterlocking or disengaging it from the screw-shaft D, as hereinafterdescribed. In using the vise above de scribed, irst adjust the jaws bythe handwheel F to about the size of the article to be secured in thejaws. Then interlock the pin d of the lever E with a hole or socket, c,of the screwshaft D by moving the lever in the proper direction to carrythe pin d toward the center of the screw-shaft, after which apply forceto the lever, as with a lever-handle attached to. the shaft of a vise,as ordinarily.

This hand-wheel is used to I The screw-shaft is thus turned by the leverE and the jaws' thereby made to more firmly gripe the article in thevise, and when a sufficient gripe is obtained then move the lever in theopposite direction to that above stated,

thereby breaking the interlock with the shaft, which leaves the leverfree to depend from the shaft. While the lever depends from thescrew-shaft, as above stated, it in no manner interferes with theordinary operation of the shaft, and, as is obvious, it is entirely outof the way as regards the work held or the movements of the workin an,while at the same time, when desired, it can be brought into action onthe screw to secure the desired leverage.

In the Figs. 3, .4, and 5 the interlock of the lever E is illustrated asobtained by aprojeetthe application of force to the lever.

In Fig. 7 is shown a construction ofthe lever `E by which the interlockof the lever and shaft is secured by sliding the pin or rod h on thelever into a notch, lor hole, or recess, i, of the screw-shaft D.

In Fig. 8 the interlock of the lever E with the shaft is shown as beingmade by setting the lever in and between any two of the series of teethK on the face of the hand-wheel F to the shaft D.

In Fig. 9 the lever E and the hand-wheel of the shaft are shown assimilarly constructed with teeth, so that by sliding the lever toward oraway from the hand-wheel it can be engaged with or disengaged from thehandwheel, and thus, through it, engaged with or disengaged from theshaft.

Under each and all the constructions and arrangements of the lever E andscrew-shaft D, or part attached thereto, hereinabove described,obviously the result aimed at by the present invention is obtained, andthey each and all embrace the invention, which, as before stated,substantially consists in the c011- struction ofthe screw-shaft of avise for the interlock of a lever therewith, and in the coinbination,with the said screw-shaft, of a lever hung loosely upon saidscrew-shaft, so as to i be readily interlocked with and disengaged fromthe sclew-shaft, as and in a manner and for the purpose described.

Having thus described my invention, what I claim, and desire to secureby'Letters Patent of the United States, is-

In combination with the movable jaw of a vise, and the screw, with orwithout the handwheel, for operating the same, the lever E, arranged tohang loosely upon the screw-shaft, and to be engaged with and disengagedfrom the screw at will, substantially as described.

Executed at Boston this 16th day of October, 1873.
